Hear Curing Sealant A002HCS57

A002HCS57 Heat Curing Adhesive

Product description

A002HCS57 is a one-component heat curing, solvent free sealant based on PVC/acrylate.

It can be applied to clean, bare steel or electrocoat and accepts powder paint either cured or wet on wet.

A002HCS57 is used in high heat applications (230°C) where resistance to heat degradation and color change is important.

Features

Adheres well to most E-coated substrates and to oily metal substrates.

Suitable for powder-coating processes.

Exposed to moisture at room temperature, the surface is cured after about 5 hours.

Suitable for sealing different metals, e.g. steel, aluminum, galvanized steel, etc.

High temperature resistance of 180-230 ℃(320-430°F), no aging and discoloration.

Spot welding still possible.

Does not contain solvents or PVC.

It can be electroplated after pre-curing and has good washability

Typical application

It is used for bonding clean steel or electrophoresis plate, and can be sprayed with powder paint after wet adhesive or curing.

It is used for sealing, waterproof, dustproof and anti-corrosion of the inner and outer welds of the car body.

Main technical parameters

Note：The above data are tested under specific conditions All technical data stated in this Product Data Sheet are based on laboratory tests only. Actual measured data may vary due to circumstances beyond our control.

Construction process

Metal Surface Preparation

This material has been developed to adhere to metals which have been cleaned, treated, and primed.

This material will not adhere to untreated metal.

For best performance, substrate should be free of contamination before material is applied.

Application

It is recommended that testing is completed on substrates to be used to validate this material prior to use.

Deviations from cure cycle may result in deviations from the shear strength which may interfere with material performance.

It can be applied with standard piston, gear or rotary pumps. It can also be applied out of cartridge tubes.

The material is homogeneous and contains no abrasives that will affect pumping equipment.

This material can be dispensed using a pumping system. This should include a high pressure ratio pump, with a follower plate and flow guns with tips appropriate to the bead size needed.

Care should be taken in system design to insure that flow restrictions are minimized. Flow restrictions occur when headers, hoses, and/or nozzles are too small for the application.

Removal

Fresh, uncured material can be removed with the aid of Isopropyl Alcohol. Large amounts of material can be removed using towels or rags and then cleaned with Isopropyl Alcohol.

Cured material can only be removed mechanically

General Information

Shutdown - For extended shutdown periods, greater than 8 hours, it is recommended that pressure be removed from the system to reduce possibility of caking in lines.

Material Purge - Regular purge and cleaning of the application system is recommended, please contact your sales representative for material requirements and instructions.

As with all materials, it is recommended that to ensure consistent material, this product is used in a First In - First Out
