COATWEL BOND 311

Structural One-component Adhesive Sealant

Product Overview

  • Room temperature hardening one-component high-performance multi-purpose adhesive specialized in high functional fields

  • Strong adhesion results in excellent adherence and sealability between structures

  • Because a load can be applied to the entire adhesive surface, the stress concentration is lower than that of drilling, bolts, and rivets, so the load can be evenly distributed. This improves the durability of the structure by improving mechanical properties such as shear strength and compressive strength

  • Fastening elements (volts, rivets, etc.) are not revealed, resulting in a clean appearance

  • Permanent elasticity can absorb fine movement between bonding surfaces, reducing noise, vibration, etc

  • Simplifying the processing and assembly of fastening elements reduces work processes, reducing cost and weight (lightening)

  • Possible to join complex shapes compared to the mechanical fastening method, so the degree of freedom of design is high

  • Based on the characteristics of the product material that combines the advantages of urethane and silicone, there is less pollution and excellent weather resistance and durability

Product Use

  • Adhesion between different metals and a wide range of materials, including metals, plastics (acrylic/PC) and rubber

  • All adhesive applications requiring initial start strength

  • Durable adhesive applications such as cold and heat repetition

  • ​Adhesion of Different Materials with Different Coefficients of Thermal Expansion

Product Features

  • Excellent adhesion to various adherend substrate surface(no primer required)

  • Excellent chemical resistance expression to acid and alkali, etc.

  • Phthalate plasticizers and solvents not included

  • Moisture hardening type                                    (resistant to vibration and impact)

  • Excellent paintability and workability product, low pollution
