- One to one mix ratio
- Room temperature curing
- Non-drip paste
- For bonding, sealing and coating
- Chemical resistant
Master Bond EP21NDFG is a two component, room temperature curing epoxy adhesive/sealant featuring outstanding physical properties, easy processing and a non-drip, paste-like consistency. This system has a non-critical one to one mix ratio by weight or volume. EP21NDFG has the unusual characteristic of being able to adjust the properties of the cured system by altering the mix ratio. Adding more of Part A (e.g. 2:1 mix ratio) will give a more rigid cure, while adding more of Part B (e.g. 1:2 mix ratio) gives a more forgiving cure. EP21NDFG produces high strength, durable bonds which hold up well to thermal cycling and resist many chemicals including water, oils, fuels, acids, bases and salts. It bonds well to a variety of substrates including metals, composites, glass, ceramics and many types of rubbers and plastics. Once cured, EP21NDFG is an excellent electrical insulator. It is serviceable over the wide temperature range of -60°F to +250°F. The color of both Parts A and Part B is amber, although, a wide variety of additional color choices are also available. EP21NDFG is primarily used in food equipment applications where there is an indirect exposure to food and related products.
- Convenient mixing: non-critical one to one mix ratio by weight or volume
- Variable mix ratio feature allows adjusting the type of cure (mentioned above)
- Easily applied; adhesive spreads smoothly; non-drip application feature
- Ambient temperature cures or fast elevated temperature cures as required
- High bonding strength to a wide variety of substrates
- Lower shrinkage upon cure
- Excellent dimensional stability with good electrical insulation properties
- Meets FDA Section 175.105 for indirect food applications
Frequently Asked Questions
Which food grade specifications does EP21NDFG meet?
EP21NDFG complies with the FDA 175.105 for indirect food applications.
Is EP21NDFG rated for direct contact with food?
Although EP21NDFG is not rated or qualified for applications involving direct food contact, it is suitable for sustained use in food equipment applications with indirect food contact.
Can EP21NDFG be used to repair items and equipment in a home kitchen?
No. EP21NDFG is only intended for industrial bonding and sealing applications and is not suitable for home use. In order to achieve optimum properties, this epoxy requires post curing (150-200°F) for at least 2 hours, and we highly recommend the use of industrial ovens for the curing process.
Is EP21NDFG rated for contact with potable water?
No. EP21NDFG is not rated or qualified for use in potable water applications.
Although EP21NDFG has passed FDA standards, how important is it for the end user to perform further testing on the final device?
It is the end user’s responsibility to consult with the appropriate agencies as well as their own legal and technical experts, in order to qualify the EP21NDFG in the context of their application, and obtain the necessary approvals for the final device.
EP21NDFG is available is various sizes and units to accommodate customer's needs.
