TR series elastic paint
Product description: TR series of elastic coatings have excellent adhesion, scratch resistance, chemical resistance, wear resistance and slippery as silk.
Main components: Saturated polyester resin, auxiliaries, organic solvents
Applicable products: Widely used in 3C electronic products and related equipment, household appliances accessories and so on.
Applicable base materials: ABS﹑PC﹑ABS+PC;if match the appropriate primer of our company also suitable for PPS﹑PET﹑TPU nylon and metal etc.
Environmental conformance: Meet the requirements of ROHS.
Important explanation: Our company have common type and high wear-resistant of the TR series for our customers to select.
Workpiece inspection --> degreasing and dedusting --> Confirmation of the furnace temperature --> painting --> inspection --> packaging for good products

1.Please stir well before use;
2.Please refer to "construction technology instruction" to remove oil, degrease and dust before use.
3. Please use 300 mesh filter net for filtering;
4.Due to the different types and forming conditions of the rubber, please confirm it fully before using the coating to ensure its adaptability.
5.When the humidity is too high, it is suggested that put into the bake road or oven to prevent blushing.
6. The coating should not be too thin, too thin to protect the film, and it is easy to affect the chemical resistance test and wear resistance.
7. When the hardener is opened, please seal it in time so as not to react with the moisture in the air.
8. The proportion of the main paint and the hardener must be weighed accurately.
9. The main paint and hardener were mixed well, must be finished it within 1 hours under room temperature, otherwise easy to get gelling, The higher environment temperature, the shorter time can be used.
10. The gun of the spraying double liquid coating must be cleaned every hour in order to prevent the clogging. At the same time, the pipe and the gun must be washed with the washing gun solvent.
11. After spraying, it is necessary to put into the oven within 60 minutes. the performance test will not be passed if stayed for a long time.
Warm reminder
Quality guarantee period: The expiration date is half a year with sealed。
Storage conditions: Stored in a cool, dry, special chemical reservoir, away from the fire source。
