High quality. PG541-7 has very low viscosity and good spray performance, applied to products with high quality requirements, such as high-gloss cabinet door panels, etc., high strength, and high heat resistance products.

Product Highlights

Vacuum blister adhesive is a milky white emulsion with very low viscosity and good spray performance. It can be used alone or with the addition of crosslinking agent U6Z.

Applications

Suitable for vacuum forming machines, bonding PVC film to substrates such as medium-density fiberboard and particleboard. Adding an appropriate amount of crosslinking agent U6Z can enhance the bonding strength and weather resistance of the PVC film on the substrate.

Product Parameters

Storage: 9 months under sealed packaging at 25°C. Store sealed in a clean, cool and dry place at a temperature between 5 and 30°C. When using, use the product that has been stored the longest first.

Notes

Precautions	1. Can be used alone or mixed with 3-5% crosslinker U6Z; 2. Spray application with a 2.0mm nozzle is recommended. The vacuum membrane adhesive has good leveling performance; apply the adhesive evenly to avoid later surface waviness on the finished product. Before applying the adhesive, the substrate surface must be completely clean and free of dust and debris to avoid later pitting on the finished product; 3. When the adhesive layer has been open for more than 30 minutes (at 20°C room temperature), use thermal activation to press the PVC onto the substrate for bonding. Pay attention to the heating temperature and pressing force to prevent PVC skin shrinkage or deformation caused by excessive temperature or pressure; 4. Stir thoroughly before use. Containers holding the adhesive must be kept tightly closed to prevent surface film formation and contamination. Do not mix with other adhesives of different properties;
Operation and Use	This product contains isocyanates. Protective gloves suitable for isocyanates should be worn. Wear safety goggles each time the product is used. The curing agent must not come into contact with water or moisture.
Cleaning	Cleaning must be performed before the system cures.
Health, Environment, and Safety	Adhesive – after curing, the adhesive can be disposed of as general non-hazardous waste. Curing agent – contains isocyanates and should be disposed of as hazardous waste. Mixed adhesive and curing agent – once fully cured, can be disposed of as general non-hazardous waste.
