Low-Odor & Eco-Friendly Properties: With ultra-low odor, it is ideal for odor and VOC-sensitive scenarios such as low-odor eco-friendly conformal coatings and anti-scorch plastic paints.

Great Chemical Resistance & Insulation Performance: It passes 48-hour salt spray test and double 85 test, and features excellent insulation, fully satisfying the protective requirements of conformal coatings.

III. FAQ

Q1: Can MR1715 be directly diluted with water?

A: No. It is only soluble in alcohols and partial ether ester solvents. Direct water addition will cause resin precipitation and failure of film formation. However, infinite water dilution is available after neutralization with an appropriate amount of amine neutralizer according to the acid value.

Q2: Is MR1715 applicable to all plastic substrates?

A: No. It shows excellent adhesion on ABS, PVC, PC, PMMA and nylon substrates, but no adhesion on PP and PET substrates. It also has no adhesion on 304 stainless steel and aluminum alloy metal substrates, and only performs well on polished tinplate, brass and glass. Substrate adhesion tests are required before formal use.

Q3: What is the salt spray resistance duration of MR1715-based conformal coatings?

A: The alcohol-soluble conformal coating formulated with MR1715 passes the 48-hour salt spray test. The actual performance is affected by formulation additives, solvent systems, film thickness and construction processes. Higher salt spray resistance can be achieved by adding cross-linking agents or functional additives.

Q4: Between MR1715 and water-based acrylic resin, which is more suitable for low-odor eco-friendly scenarios?

A: Both belong to low-odor systems. MR1715 adopts alcohol solvents, eliminating common problems of water-based systems such as flash rust and humidity-dependent drying performance, and delivers more stable adhesion on plastic substrates. Water-based resins feature lower VOC emissions but have strict construction limitations. The selection should be based on actual substrates and construction environments.

Q5: How to adjust the high viscosity of MR1715 during construction?

A: The viscosity can be adjusted by adding co-solvents such as absolute ethanol, propylene glycol methyl ether or BCS. Add the solvent gradually with uniform stirring to avoid resin precipitation caused by excessive one-time addition, and pay attention to the influence of solvent volatilization rate on film leveling performance.

IV. Summary

KDD MR1715 alcohol-soluble acrylic resin features low odor, environmental friendliness, strong plastic adhesion and outstanding chemical resistance, making it perfectly suitable for alcohol-soluble conformal coatings, low-odor plastic paints and baking paints. It solves the pain points of traditional solvent-based resins such as strong odor and high VOC, and avoids the drawbacks of water-based resins including complicated construction and poor substrate compatibility. It is a reliable choice for eco-friendly coating formulations.
