BECKOPOX™ EP 387w/52WA is internally plasticized and therefore more flexible than BECKOPOX™ EP 384w/53WAMP. Pigments and fillers can be dispersed in BECKOPOX™ EP 387w/52WA.
Applications & Uses
- Applications
- Compatible Polymers & Resins
- Coating Type
- Special Properties and Uses
Internally plasticized solid resin-Type 1-dispersion with improved shear stability, e. g. for water reducible fast drying anticorrosion primers and coatings for plastics
- Suggested Uses and Processing Information
- BECKOPOX™ EP 387w/52WA is an internally plasticized type 1solid epoxy resin as aqueous dispersion.
- Formulated together with adequate curing agents such as e. g. BECKOPOX™ VEH 2188w/55WA it is suited for corrosion protection primers with very good adhesion to most metallic substrates. It is also suitable for use in single coat and decorative systems for metallic substrates. For optimium corrosion protection it is recommended using 75% of the stoichiometric curing agent quantity.
- Dispersion of pigments and fillers can be done in BECKOPOX™ EP 387w/52WA if the temperature does not exceed 40°C.
- The formulated paint stability can be influenced by the additives used so that it is important to investigate their suitability thoroughly; such additves should not contain functional groups capable of reacting with epoxy groups.
MIXING RATIO AND POT LIFE
A blend of 100.0g BECKOPOX™ EP 387w/52WA 28.5g BECKOPOX™ VEH 2188w/55WA 20,0g deionized water has a pot life at 23°C of approx. 6 hours. It is necessary to use the material within the stated time limit. The substrate temperature should not be below 12°C and the relative humidity not above 80%.

Storage & Handling
- Shelf Life
- 1 Year
- Storage and Handling
- At temperatures up to 30°C storage stability packed in original containers amounts to at least 365 days.
- It is important to protect BECKOPOX™ EP 387w/52WA from frost and direct sunlight; at low temperatures it has to be stored under frostproof conditions.
- As a result of the high solids content of the product and the solid resin character of the polymer, the product tends to form a tiny skin upon foaming and temperature changes during storage. Therefore filtration of the product (without heating) before applied by the end-user is recommended. The viscosity of BECKOPOX™ EP 387w/52WA can drop during storage.
- Lowest storage temperature: 5°C
- When handling and processing epoxy resins and hardeners, please notice the information in the material saftey data sheet (MSDS) and observe the rules and regulations established by local authorities.
