Bio-Based Epoxy Resin is the Entropy Resins ONE laminating system for manufacturers seeking reliable composite processing with a measured renewable-carbon contribution. Marjan Polymer Industries supplies ONE resin in Pakistan with ONF Fast or ONS Slow hardener and the current technical and safety documentation.
Product Identity
The manufacturer designation is Entropy ONE High Biobased Laminating Epoxy Resin. It is a general-purpose two-component system for fibre-reinforced laminates, coatings and compatible adhesive applications. The system is designed for low viscosity, fibre wetting and quick air release.
Bio-based does not mean biodegradable or harmless. It describes the measured renewable origin of part of the organic carbon. Normal epoxy handling, cure validation and end-of-life controls still apply.
System Options
- ONE + ONF Fast: shorter working and tack-free time for small-to-medium laminating jobs.
- ONE + ONS Slow: longer working time for larger laminates, warmer shops or more complex reinforcement placement.

Typical Applications
- hand-laminated and vacuum-bagged composite parts;
- glass-, carbon- and compatible natural-fibre laminates;
- general composite coatings and sealing work;
- compatible adhesive and wood/composite constructions after testing;
- sustainability-led product development in Pakistan.
Recommended Processing Workflow
- Define the requirement: specify laminate, service temperature, mechanical target and sustainability claim.
- Select hardener: match ONF or ONS to the part size and shop temperature.
- Condition and prepare: keep reinforcement, tools and moulds clean, dry and at the qualified temperature.
- Measure: use 100:43 by weight or accurate 2:1 volume metering.
- Mix and laminate: scrape the container thoroughly, wet reinforcement uniformly and remove trapped air.
- Cure: protect the laminate during the full cure and apply a qualified post-cure when required.
- Verify: test cure, laminate quality and finished-part properties before production release.
Sustainability Claims and Documentation
Claims must distinguish resin-package content from the final mixed system and final composite. Reinforcement, fillers, consumables, waste and energy all affect the finished part’s footprint. Use the current supplier documentation and ASTM D6866 values; do not market the product as biodegradable or carbon-neutral without separate evidence.
Storage and Safety
Store sealed components under current manufacturer conditions. Wear chemical-resistant gloves and eye protection and provide ventilation. Mixed epoxy can exotherm in bulk. Review the current ONE resin and ONF or ONS hardener safety data sheets before use.
Information Required for a Quotation
Provide the application, reinforcement, process, laminate area and thickness, workshop temperature, preferred working time, mechanical and sustainability targets, trial or production quantity and delivery city. MPI will confirm the system, pack and documentation.
Frequently Asked Questions
What is Entropy ONE Bio-Based Epoxy Resin?
ONE is a general-purpose high-biobased laminating epoxy system for composite laminations, coatings and compatible adhesive work, supplied with ONF Fast or ONS Slow hardener.
What does bio-based mean for this epoxy?
It means a measured share of the organic carbon comes from renewable biological sources rather than fossil feedstock. It does not mean the cured epoxy is biodegradable, compostable or non-hazardous.
What is the published biobased content?
The product is presented as a USDA Certified BioPreferred product with 30% biobased content. The technical data also lists mixed biobased carbon values of 28% with ONF Fast and 21% with ONS Slow under ASTM D6866.
What is the mixing ratio?
Both ONE systems use 2:1 resin to hardener by volume and 100:43 by weight.
Which hardener provides more working time?
ONS Slow has a published pot life of approximately 43 minutes at 25°C, compared with 18 minutes for ONF Fast under the stated test conditions.
What is ONE used for?
It is intended for general composite laminations, coatings and compatible adhesive applications where fibre wetting, quick air release and reduced fossil-derived content are important.
Is it suitable for clear decorative casting?
ONE is a laminating system, not a dedicated deep-casting resin. Use a qualified clear casting system when long open time, high clarity and thick-pour exotherm control are required.
How long does the system take to cure?
The manufacturer lists seven days at 25°C for full cure and recommends post-curing when higher thermal or mechanical properties are required.
Does bio-based epoxy require normal safety controls?
Yes. Bio-based content does not remove epoxy hazards. Wear suitable gloves and eye protection, provide ventilation and follow the current resin and hardener safety data sheets.
What does MPI need for a quotation?
Provide the laminate or coating application, reinforcement, part size, process, desired working time, sustainability target, quantity and delivery city in Pakistan.
