About This Product

Product Info


K-FLEX® 320 Contact Adhesive is an amber-colored, fast drying neoprene contact adhesive that is ideal for bonding porous or non-porous material. This adhesive has a thicker consistency, is not runny and can be applied with a brush or a roller.

K-FLEX® 320 Contact Adhesive is a reliable way to join seams and butt joints of elastomeric pipe and sheet insulation.
It is ideal for bonding porous and non-porous materials, as it is not absorbed easily. It is suitable for line temperatures up to 220°F (104°C) on applications requiring bonded seams and joints. When the adhesives are applied to large flat or curved surfaces, it is suitable for temperatures up to 200°F (93°C).

The products are supplied in a variety of sizes ranging from pint brush top containers to gallon containers. Larger containers are available upon request.

Thinning the adhesive is not recommended. Common lacquer thinners can be used for clean up.
Warning: this product contains a chemical known to the State of California to cause cancer.
