precote 15
Coating for Sealing of Threaded Joints DVGW certified
Description
precote 15 is a non-reactive coating used for immediate sealing of cylindrical and conical threads. The coating is dry, with good adherence and elastic.
Application
precote 15 is used as a coating for assembly components, e.g. screws, studs, plugs and pipe threads, both cylindrical/cylindrical and cylindrical/conical parts. precote 15 can also be applied to flange head screws or plugs with collar for under head sealing and used as a sealing material for rivets.
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
- No leakage immediately after assembly
- Controlled thread friction values during assembly
- Constant assembly properties
- Forms a dry to the touch and elastic coating
- Good thermal and chemical resistance
- Can be applied to metallic and non-metallic surfaces
- 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.
