Application Instructions
- Surface Preparation: Ensure bonding surfaces are clean, dry, and free from oil, dust, and contaminants. Degrease with appropriate solvent if necessary.
- Mixing: Combine the main agent and curing agent at the specified ratio (1:1 or 2:1 by weight). Stir thoroughly until uniform in color with no streaks.
- Application: Apply adhesive evenly across the bonding surface using a brush, roller, or trowel. Single-layer thickness should be 0.5mm to 2mm.
- Bonding: Allow the adhesive to become slightly tacky, then press the two surfaces together with appropriate pressure.
- Curing: Maintain pressure until fully cured. Surface dry in 2-4 hours (25°C); full cure in 24-48 hours (25°C).
- Multi-Layer: For multi-layer applications, wait until the previous layer is surface-dry before applying the next.
Important Safety Notes
- Always use in a well-ventilated environment to avoid prolonged inhalation of adhesive vapors.
- Avoid contact with eyes and skin. In case of contact, rinse immediately with copious water and seek medical attention.
- Store in a cool, dry, well-ventilated place away from fire and heat sources.
- Always conduct a small-area test before full-scale application to verify bonding performance.
Frequently Asked Questions
What makes GM-DW different from standard industrial adhesives?
GM-DW is specifically engineered for cryogenic environments down to -196°C. Unlike conventional adhesives that become brittle and fail at extreme low temperatures, GM-DW maintains its flexibility and high bond strength across a temperature range of -196°C to 105°C, making it uniquely suited for LNG facilities, cryogenic storage, and Arctic industrial applications.
Is GM-DW environmentally safe?
Yes. Independent laboratory testing confirms that GM-DW contains no detectable levels of free formaldehyde, benzene, toluene, xylene, or dichloromethane. Its TVOC of 671 g/L is below the regulatory limit of 700 g/L, meeting stringent environmental compliance standards.
Can GM-DW be used on PTFE (Teflon) surfaces?
Yes. GM-DW is compatible with a wide range of substrates including PTFE, polyimide, stainless steel, aluminum, copper, ceramic, glass, and composite materials. Its exceptional flexibility ensures reliable bonding even on traditionally difficult-to-bond surfaces.
What is the recommended curing time in cold environments?
At 25°C, surface dry time is 2-4 hours and full cure takes 24-48 hours. In low-temperature or high-humidity conditions, curing time may be extended. We recommend planning application schedules accordingly and conducting site-specific tests.
Does the bonded joint require additional protection after curing?
No. Once fully cured, GM-DW forms a high-strength bond that requires no additional protective layer. This simplifies workflow, reduces material costs, and improves overall project efficiency while simultaneously preventing insulation-layer corrosion and ensuring system gas-tightness.
