Q1: What type of epoxy systems is BC900 designed for?
A: BC900 is specifically formulated as a curing agent for waterborne epoxy resin systems used in domestic and light-commercial flooring applications, including self-leveling underlayments, decorative coatings, and low-VOC protective topcoats.
Q2: How does BC900 contribute to low-odor and low-VOC performance?
A: As a non-solvent, amine-based waterborne curing agent, BC900 eliminates the need for volatile organic co-solvents during formulation, supporting compliance with indoor air quality requirements for residential environments.
Q3: Can BC900 be used with standard waterborne epoxy resins?
A: Yes — BC900 is compatible with common bisphenol-A and bisphenol-F based waterborne epoxy dispersions. Optimal performance requires verification of pot life, film formation, and cure kinetics within the specific resin system and application conditions.
Q4: What is the typical dosage range for BC900 in formulated systems?
A: Dosage depends on the epoxy equivalent weight of the resin and desired performance profile, but BC900 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the total formulation — and should be optimized through lab-scale trials.
Q5: Does BC900 require special storage or handling precautions?
A: BC900 should be stored in sealed containers at temperatures between 5°C and 30°C, protected from freezing and prolonged exposure to moisture or high humidity. Standard industrial hygiene practices for amine-containing materials apply during handling.
