3M Flexible Potting and Encapsulating Compound Resin bag Scotchcast 40 426 g Light Yellow 426 g Resin bag Scotchcast 40 426 g

3M Resin bag Scotchcast 40 426 g flexible potting and encapsulating compound is a polyurethane resin designed to cure at room temperature, offering excellent electrical insulation and mechanical protection for low voltage cable joints. This resin comes in a light yellow liquid form with a 426 g package size. It is engineered for both indoor and outdoor applications, including underground and submerged environments, ensuring reliable performance in demanding conditions.

The compound provides excellent adhesion to a wide range of metals and plastics, making it versatile for various applications. Its hydrophobic behavior during curing minimizes moisture absorption, which improves the longevity and reliability of encapsulated components in damp and wet environments. The low exothermic reaction temperature helps prevent damage to installed components during curing.

Featuring a high dielectric strength of 36 kV/mm, Scotchcast 40 resin ensures superior electrical insulation, preventing electrical breakdowns in low voltage systems. Its strong impact resistance contributes to robust mechanical protection over extended periods, enhancing joint durability.

Excellent adhesion to metals and plastics. Hydrophobic to reduce moisture ingress during cure. Low heat generation during curing minimizes damage risk. High dielectric strength for electrical insulation. Strong mechanical impact resistance.

Closed mix and pour application system for ease of use. Resistant to moisture in underground and submerged installations. Low volume shrinkage at 3.4% maintains encapsulation integrity. Wide operating temperature range from -40°C to 110°C.

Mixing ratio 100:46 ensures consistent curing properties.

This resin’s pot life varies with temperature, approximately 35 minutes at 5 °C, 18 minutes at 23 °C, and 9 minutes at 40 °C, allowing rapid yet controlled application depending on environmental conditions. To maintain product integrity, store sealed between 10 °C and 40 °C with humidity below 75%. The product is manufactured in Belgium under the brand 3M and complies with standards including EN 166, RoHS, and REACH, making it suitable for industrial, electrical, and manufacturing uses.
