Three Common Questions About Teflon Coating

Today, Chongqing Teflon Coating is here to discuss the three common issues with Teflon coating and their solutions.

Phenomenon: Granulation, Spraying

Reason: Teflon Coating Experts Explain - Unclean work sites lead to dust mixed with paint; paint left too long after mixing, causing copolymer particles to form between the paint and hardener; too little paint output from the spray gun and excessive pressure, resulting in poor paint atomization or the spray gun being too close to the surface.

Solution: Clean the paint spray room, cover the paint buckets; mix the paint properly, avoid leaving it for too long; adjust the spray gun to ensure optimal working condition, and set the nozzle distance from the surface to be between 20-50 cm.

2. Phenomenon: Drizzle

Reason: A Teflon Coating Expert Explains - Too much thinner causes the paint to have low viscosity and lose adhesion; excessive oil output, too close to the surface or the spray speed is too slow; too much paint applied each time or too short intervals between re-spraying; uneven surface, especially streamlined shapes prone to sagging.

Solution: Mix according to specifications; control the oil output to ensure increased spray gun speed; do not apply too thick a coat of paint, two coats with an interval between them are ideal; control the oil output to reduce film thickness; mix as per instructions.

3. Phenomenon: Orange Peel

Reason: A Teflon Coating Expert Explains That Too Much hardener causes the paint film to dry too quickly and react violently; excessive spray pressure wrinkles the paint film, preventing it from leveling; and high temperatures in the work area lead to剧烈 reaction of the paint film.

Solution: Follow the instructions for mixing ratio; adjust the pressure, not too high; and pay attention to the site temperature, consider adding a slow-drying thinner to control the drying speed.
