precote 19-2
Clamp Coating for Threads
Description
precote 19-2 is a non-reactive coating that offers immediate clamping of cylindrical threads. The coating is dry, tack-free and with good adherence.
Application
precote 19-2 is used as a coating for assembly components, e.g. screws and studs in cylindrical/cylindrical pairing, where controlled and high initial installation torque for adjustment is needed. Furthermore precote 19-2 can be used as captive coating or transport lock. precote 19-2 is particularly suitable for clamping on screws > M4.
The coating can be used in all kind of assembly procedures, particularly for serial production.
Areas of application are electronics, two wheel and automotive industry, household appliances, office machines, computer industry, electric motors, e-mobility, etc.
Properties
- Clamping immediately after assembly
- Constant assembly properties
- Dry to the touch coating
- Can be applied to metallic and non-metallic surfaces
- Good chemical resistance
- Reusable on a limited basis
- Non-hazardous

Note
Since we do not know which thread types, dimensions, materials, pairings, surface conditions, etc. prevail, it is absolutely necessary to carry out appropriate control tests before a general application in order to convince yourself of the desired function under the respective practical conditions before series use. Our warranty extends to the perfect quality of precote® deliveries. Since both the precote® processing by the coating partner and the application of precote®-coated parts are beyond our control, we cannot assume any warranty for the quality of precote®-coated parts and the composites produced with them. We only accept liability for the suitability of our products for certain applications and for certain properties of the products if these have been agreed in writing in individual cases. In any case of justified warranty claims, these are limited to the delivery of defect-free replacement goods or, if this rectification should fail, to the reimbursement of the purchase price. All further claims, in particular liability for consequential damages, are generally excluded.
