PRODUCT DESCRIPTION

DEDT 3242 is a single component anaerobic threadlocking material, which is thixotropic and develops

medium strength . The product cures when confined in the absence of air between close fitting metal

surfaces.

TYPICAL APPLICATIONS

*Prevents loosening and leakage of threaded fasteners.

*Pump and motor mounting bolts.

*Engine rocker nut

*Situations were disassembly with hand tools is required.

CURE SPEED VS. SUBSTRATE

The rate of cure will depend on substrates involved.

Substrate Fixture time/Full cure

Steel 15min/24hrs

Brass 20min/24hrs

Zn Dichromate 30min/24hrs

Stainless Steel 40min/24hrs

CURE SPEED VS. BOND GAP

The rate of cure will depend on the bondine gap. The bondlines result in high cure speeds, increasing the

bond gap will decrease the rate of cure.

CURE SPEED VS. ACTIVATOR

Where cure speed is unacceptably long due to large gaps, applying activator to the surface will improve

cure speed, But may also impair overall adhesive performance and therefore testing is recommended to

confirm effect.

CURE SPEED VS. TEMPERATURE

The rate of cure will depend on the ambient temperature. High temperature tend to increase the speed

GENERAL INFORMATION

This product is not recommended for use in pure oxygen rich systems and should not be selected as sealant

for chlorine or other strong oxidizing materials.

Where aqueous washing systems are used to clean the surfaces before bonding. It is important to check for

compatibility of the washing solution with the adhesive. In some case, these aqueous washes can affect the

cure and performance of the adhesive.

This product may not be compatible with plastics,(particularly thermoplastic materials where stress

cracking of plastic could result). Users are advised to confirm compatibility of the product with such

substrates.

DIRECTIONS FOR USE

For best results, surfaces should be clean and free of grease. 3243 should be applied to the bolt in adequate

quantity to fill all engaged threads. 3243 performs best in thin bond gaps, (0.05mm). Very large thread sizes

may create large gaps which will affect cure speed and strength. This product is designed to give controlled

friction, (torque/tension ratio), during assembly. In cnitical tightening applications this ratio should be

confirmed.

PRODUCT STORAGE

Product should be stored in a cool, dry location in unopened containers at a temperature between containers

at a temperature between 46℉ (8℃)and 82℉ (28℃)unless otherwise stated. To prevent contamination of

unused product, do not return any material to its original container.
