SINA Industrial Grade Adhesive-SP2-200

Polychloroprene solvent based easy flowing contact adhesive, is a mixture of polymers, industrial resins and dissolved stabilizers in a mixture of solvents and is used for bonding of absorbing and non-absorbing surfaces where quick, high-strength, permanent bonds are needed. It has high initial bond strength, long tack time and is water resistant.

Viscous liquid like honey.

12 months, if stored in original closed packing in a dry and cool place away from direct light and heat.
Use the adhesive above 15ºC.
Surfaces to be bonded should be free from dust, dirt and contaminants such as oil and grease.
The adhesive is usually applied by brush or roller coater.
Stir well before using.
Apply an even coat on both surfaces.
Let it dry for about 15-20 minutes.
Join surfaces together and apply pressure over the entire working area.
With the use of porous materials, two coats of the adhesive are often suggested.
In case of working at low room temperature, it is generally necessary to warm up the gluey materials to get surfaces tacky again.
  1. Uncured adhesive can be cleaned with Acetone
  2. Cured adhesive is removable with a hand tool
