Product Description
3M™ Scotch-Weld™ 3532 Series urethane adhesive is a two-component formulation such as part-A and part-B. The part-A is brown in color, while part-B is off-white in color. Polyol base part-A has a vapor pressure less than or equal to 27 psia at 131 degrees F, specific gravity of 1.35 and a boiling point temperature rating of 406 degrees F. The isocyanate accelerator part-B has a vapor pressure less than or equal to 27 psia at 131 degrees F, specific gravity of 1.31 and a boiling point temperature rating greater than or equal to 250 degrees F. Part-A of the adhesive has a flash point greater than or equal to 201 degrees F, while polyester odored part-B has greater than or equal to 200 degrees F for safe use. The liquid adhesive comes in a 2-fluid ounce container. It withstands shear strength of 240 psi at 100 degrees F for 30 minutes. This product requires 24 hours for curing and withstands a temperature of 60 to 80 degrees F.
Features:
- Provides extremely tough and semi-flexible bonds
- Flexible at low-temperature
- Viscosity of 15,000 to 40,000 centipoises for part-A and 10,000 to 40,000 centipoises for part-B
- Density of 1.35 grams per milliliter for part-A and 1.31 for part-B
Benefits:
- Ideal for vertical and other applications that require no slumping or sagging of the adhesive bead
- Helps in bonding dissimilar substrates
Applications:
- Semi-flexible plastic or composite bonding
- Flexible for mounting brackets on thin panels or mirrors without read-through, bonding rough fabrics to rubber for conveyor belts, bonding wood, metal or composite door frames to wood or other surfaces
