| 1 | Neutral-Cure Silicone | Exterior glazing, sanitary joints, general weather sealing, and bonding near sensitive metals. | Clear or translucent; may remain slightly hazy in thick sections. | Moisture-cure; skin usually forms in approximately 10–30 minutes, with about 2–3 mm curing per 24 hours depending on humidity, temperature, and joint depth. | Commonly about −50°C to 150°C after full cure; verify the product technical data sheet. | Glass, ceramic, anodized aluminum, many metals, painted surfaces, and some plastics after compatibility testing. | Excellent weathering and UV resistance; flexible; low odor compared with acid-cure silicone; good movement capability. | Usually not paintable; adhesion to polyethylene, polypropylene, PTFE, oily surfaces, and some untreated plastics is poor. | Keep sealed in a cool, dry location, normally within the supplier’s stated storage range. Protect cartridges from freezing, heat, puncture, and prolonged sunlight; ship according to the current safety data sheet. | Use ventilation, gloves, and eye protection. Apply to clean, dry surfaces; avoid sealing trapped moisture and allow full cure before placing the joint under load. |
| 2 | Clear Hybrid MS-Polymer Sealant | Multi-material assembly, construction joints, interior finishing, and applications requiring a paintable flexible seal. | Clear to translucent; transparency can vary with thickness and humidity. | Moisture-cure; typical skin time is approximately 10–30 minutes and full cure often takes 24–72 hours, depending on joint size and conditions. | Often about −40°C to 90°C or higher, depending on formulation. | Concrete, masonry, wood, glass, metals, painted materials, and selected plastics after adhesion testing. | Strong adhesion to many building materials; flexible; commonly low odor; many grades accept compatible paints. | Some grades become less transparent in thick beads; performance varies widely between formulations; not every grade is suitable for continuous immersion. | Store upright, tightly closed, and protected from moisture. Avoid hot containers and long exposure to sub-zero temperatures. Check shelf life and transport classification before export. | Wear gloves and safety glasses; provide ventilation. Test paint compatibility and adhesion on a small area before production use. |
| 3 | Clear Polyurethane Sealant | High-strength joints, vehicle and equipment assembly, flooring details, and joints exposed to vibration. | Clear or amber-translucent; color may change slightly with age or UV exposure. | Moisture-cure; skin formation is often approximately 30–90 minutes, with full cure commonly taking 2–7 days depending on thickness and humidity. | Frequently about −40°C to 90°C; some specialized grades have wider ranges. | Wood, concrete, metals, glass, painted surfaces, and selected plastics with suitable primers or surface preparation. | Good mechanical strength, abrasion resistance, flexibility, and adhesion to porous construction materials. | Clear grades may yellow or degrade under prolonged UV exposure; moisture sensitivity and limited shelf life can be concerns; some formulations contain reactive isocyanates. | Keep containers dry and sealed. Prevent exposure to humidity during storage and transit; use moisture-resistant packaging and follow the safety data sheet for international transport. | Use chemical-resistant gloves, eye protection, and adequate ventilation. Avoid skin contact and do not use in poorly ventilated occupied areas until cured. |
| 4 | Clear Acrylic Sealant | Interior finishing, trim, crack filling, and joints that may need to be painted after application. | Clear or translucent; generally becomes less noticeable after drying. | Water-based grades dry through water evaporation; surface drying may take approximately 30–60 minutes, while deeper curing can take 24–72 hours. | Commonly about −20°C to 80°C after drying, depending on formulation. | Drywall, plaster, wood, masonry, concrete, and painted interior surfaces. | Low odor; easy cleanup while wet; generally paintable; convenient for indoor decorative work. | Lower movement, water, and weather resistance than silicone or hybrid sealants; unsuitable for permanently wet joints unless specifically rated. | Protect from freezing and excessive heat. Keep containers closed to prevent water loss and skin formation; confirm whether the formulation is regulated as a water-based preparation. | Use gloves and normal workplace ventilation. Apply only to clean, dry, stable surfaces and allow drying before painting or exposure to water. |
| 5 | Clear Butyl Sealant | Removable or pressure-sensitive sealing, window interfaces, roofing details, and low-movement joints. | Clear to translucent and permanently tacky or rubber-like, depending on formulation. | Typically remains pressure-sensitive rather than fully curing; sealing performance develops as the material conforms to the joint. | Often about −30°C to 90°C, subject to formulation and load conditions. | Glass, metal, coated panels, roofing membranes, and some plastics after compatibility testing. | Very good water and vapor resistance; remains flexible; useful where future removal or repositioning may be required. | May attract dust; limited structural strength; can creep under sustained heat or load; often difficult to paint cleanly. | Store flat or upright as directed, away from heat and direct sunlight. Keep release liners and packaging intact to prevent contamination and blocking during shipment. | Wear gloves because the material is difficult to remove from skin. Clean surfaces thoroughly and avoid using it where a structural or permanently cured bond is required. |
| 6 | Two-Part Clear Epoxy Adhesive Sealant | Rigid bonding and sealing of small components, decorative assemblies, electronics housings, and non-flexing joints. | Water-clear to pale amber; clarity depends on resin, hardener, mix ratio, and aging. | Chemical reaction after mixing; working time may range from approximately 5–60 minutes, with handling strength commonly developing within hours and full cure in about 24–72 hours. | Often about −40°C to 100°C after full cure; confirm the specific grade. | Glass, ceramics, metals, wood, and selected rigid plastics after cleaning and abrasion where appropriate. | High bond strength; good gap filling; excellent resistance to many chemicals and moisture after proper cure. | Brittle compared with elastomeric sealants; limited movement capability; mixing errors can prevent proper cure; some grades yellow with UV exposure. | Store components sealed at the stated temperature and protect from moisture. Package securely to prevent leakage or accidental mixing; review transport rules for resin and hardener components. | Wear nitrile gloves, eye protection, and suitable ventilation. Mix only the required amount at the specified ratio and avoid direct skin contact with uncured resin or hardener. |
| 7 | Acetoxy-Cure Silicone | Low-cost general sealing for glass, ceramic, aquariums or enclosures where acid-cure compatibility is confirmed. | Clear and glossy after cure; thick applications may appear slightly translucent. | Moisture-cure; skin usually forms in approximately 5–20 minutes, with roughly 2–3 mm curing per 24 hours under typical conditions. | Commonly about −50°C to 150°C after full cure, depending on formulation. | Glass, ceramic, glazed tile, and some non-porous surfaces; always test metals and plastics before use. | Fast skin formation; good flexibility; strong adhesion to glass and ceramic; good resistance to water, weathering, and UV exposure. | Releases acetic acid during cure, which can corrode some metals and irritate sensitive materials; generally not suitable for concrete, marble, limestone, or many painted surfaces without testing. | Keep sealed, dry, and within the recommended storage temperature. Protect from heat and moisture; ensure labels, batch information, and safety documents remain available for international shipments. | Provide ventilation and wear gloves and eye protection. Expect a vinegar-like odor during cure; avoid enclosed occupancy until the odor has dissipated and the sealant has cured. |
