Installation
K-FLEX K-414 Contact Adhesive should be applied between 4oC and 38oC ambient temperatures and allowed to dry for 24 hours before equipment operation. 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 adhesive tested to be sure the insulation will not lift off after application. The adhesive should be thoroughly mixed. A thin even coat of adhesive should be brushed, rolled, or sprayed on both surfaces to be joined. The adhesive films should be dry to the touch, but tacky, before joining the surfaces. The insulation should be in the desired position before the adhesive surfaces make initial contact, since the adhesive 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. Protective coatings can be applied to applications with bonded joints and seams, after allowing 24 hours of dry time. Applications such as large tanks, or vessels where full adhesive coverage is required, must be allowed to dry 7 days before applying a protective coating. Thinning the adhesive is not recommended. Common lacquer thinners (Xylol or Trichloroethylene) can be used for cleanup. Avoid heat, sparks, and open flames, and use only proper ventilation. Close the container after use.
Caution: Adhesive contains notable solvents and containers when not in use, should be kept closed. Keep adhesive away from sparks and open flames. Use adequate ventilation and avoid excessive contact with the skin.
K-Flex K-414 Adhesive
Application
K-FLEX K-414 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 curved surfaces, it is suitable for a service temperature range from -30°C to +100°C.
The product forms a resilient, flexible, moisture and heat-resistant bond when used with elastomeric products. Low viscosity allows it to be applied easily and ensures 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.).
