APPLICATIONS
K-FLEX K-996 Contact Adhesive is recommended for applications with service temperature up to +120°C on applications requiring bonded seams and joints. When the adhesive is applied directly to large flat or curve surfaces, it is suitable for a service temperature range of -30°C to +100°C. The product forms a resilient, flexible, moisture and heat-resistant bond when used with elastomeric products. A low viscosity allows it to be applied easily and ensure maximum effective contact surfaces. It is ideal for bonding porous and non-porous materials, as it will not be absorbed easily, and may be used for bonding elastomeric insulation products to a variety of materials (i.e., other elastomers, metal, concrete, etc.).
 
INSTALLATION 
For proper adhesion, the surfaces to which the insulation is to be applied must be thoroughly cleaned, dry and unheated. Primed and painted surfaces should be adhensive tested to be sure the insulation will not lift off after application. The adhesive should be thoroughly mixed.
 
Brush or roll a thin even coat of adhensive on both surfaces to be joined. Allow the adhesive films to become dry to the touch, but tacky, before joining the surfaces. Press the two surfaces together. Be sure the insulation is in the desired position before the adhensive surfaces make initial contact, since the adhensive forms an instant bond, and repositioning after contact is difficult. Moderate pressure should then be applied to the entire bonding area to ensure complete contact. Avoid heat, sparks, and open flames, and use only proper ventilation. Close container after use.
