KF-EF100 Elastic Exterior Wall Paint
KF-EF100 Elastic Exterior Wall Paint uses elastic acrylic emulsion as the base coating, with elongation at break greater than 300%, capable of bridging base cracks smaller than 2mm. The elastic paint film expands and contracts with temperature changes without cracking, integrating waterproofing and breathability. Widely used for exterior wall waterproofing and crack-resistant decorative coatings, especially suitable for large temperature differences/coastal areas/and old wall renovation projects.
ProductsOverview
Elastic Exterior Wall Paint is a high-performance professional coating product developed and produced by KeXin New Material. Scientifically formulated with high-quality resins and imported pigments and fillers, it offers excellent adhesion, durability, and application performance. Widely used in industrial manufacturing, architectural decoration, automotive transportation, and other fields.
As a source coating factory, KeXin New Material strictly implements the ISO9001 quality management system for Elastic Exterior Wall Paint from formula design, raw material procurement to production filling. The product has passed ROHS, REACH and other environmental regulation certifications. Free sample testing and on-site guidance by technical engineers are provided.
Why choose an elastic exterior wall paint?
CoreAdvantages
300% Elastic Elongation · Bridges Cracks
After curing, the elastic acrylic emulsion forms a highly elastic continuous coating with elongation at break greater than 300%. It can effectively bridge base cracks smaller than 2mm, expanding and contracting with temperature without cracking or peeling. Solves the problem of cracking and water seepage on exterior walls caused by temperature differences/settlement/material shrinkage.
Integrated waterproof-breathable system
The coating is continuous and dense, impermeable for 24h, with water pressure resistance greater than 0.3MPa. At the same time, it maintains breathability with a water vapor transmission rate greater than 120g per square meter per day. Moisture inside the wall can freely evaporate without blistering or peeling. One coating achieves the triple functions of waterproofing + crack resistance + decoration.
Weather Resistant and Freeze-Thaw Resistant · Suitable for All Climates
Resistant to artificial aging for more than 1500h and freeze-thaw cycles for more than 50 times. At -30 degrees low temperature, the paint film remains elastic without brittle cracking. Alkali resistance for 96h with no abnormality, salt spray resistance greater than 500h, suitable for use in coastal high-salt fog areas.

Frequently AskedFAQ
ApplicationProcess
Surface preparation
Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。
Primer / pre-treatment
Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.
Main-coat application
Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.
Curing process
Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.
Inspection & acceptance
Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
