Loctite 4204 High Thermal Resistance Clear - 20G Bottle

Loctite 4204 is a colourless, high viscosity instant adhesive by Henkel, engineered for bonding small to medium parts. The product is ethyl-based and toughened with elastomers. This innovative formulation grants the adhesive flexibility, superior impact resistance, and enhanced tolerance to heat and humidity. These qualities make Loctite 4204 an ideal choice for applications where durability is paramount. The product is compatible with a variety of materials, including metals, rubbers, and plastics, offering a seamless and virtually invisible bond.

Loctite 4204 cures rapidly when confined between two surfaces. This adhesive has been formulated to initiate the curing process through atmospheric moisture. While functional strength is achieved in about 10-30 seconds, the adhesive continues to cure for at least 24 hours before reaching full chemical and solvent resistance. For those working with polyolefins, Loctite 4204 can be paired with Loctite SF 770 or SF 7239 Primer for optimal results.

• High viscosity
• Solvent-free
• Ideal for bonding medium to small-sized parts
• Provides increased flexibility, impact resistance and tolerance to heat and humidity
• Fixture time ranging from 10 to 30 seconds

How to use Loctite 4204:

1. Clean surfaces before applying the product.
2. Apply Loctite 4204 to bond surfaces.
3. Assemble components carefully. The short fixture time leaves little opportunity for adjustment.
4. Hold together or clamp bonds until the adhesive has fixtured.
5. Allow product to develop full strength before subjecting to any service loads. This will usually take about 24 hours.

Storage

Store Loctite 4204 in the unopened container in a dry location. Optimal Storage: 2° C to 8° C. Storage below 2° C or greater than 8° C can adversely affect product properties.
