The binder behind every brake pad and grinding wheel
Phenolic resin holds a friction material or bonded abrasive together: hot-pressed with fibres, fillers and abrasives, it melts, wets every particle and cures into a rigid matrix that keeps its strength at braking and grinding temperatures.
The ELRIBOND range covers novolacs with and without hexamine, rubber, organic, inorganic and CNSL-modified grades, high-bond novolacs, resols, liquid CNSL resins and CNSL friction particles, each with published typical properties.

Unmodified novolac powder resins with hexamine
Straight phenol-formaldehyde novolacs, ground and blended with hexamine. They are the standard binder for brake pads, drum linings, clutch facings and bonded abrasives because of their heat resistance and wear behaviour. All grades are low in free phenol, and dust-free versions are available. Pick by flow first, then by cure speed.

Hexamine-free novolac resins
Novolacs supplied without curing agent, for manufacturers who add their own hexamine or another hardener, and for refractory and carbon-bonded products where you control the cure yourself.

CNSL modified powder resins
Cashew nut shell liquid (CNSL) is a natural phenol and the raw material Elrisa is built on. Replacing part of the phenol with CNSL gives a more flexible matrix for better comfort, a higher friction level and better water repellence. Available in several degrees of modification.

Inorganic modified powder resins
For high-temperature duty. Phosphorus (P) modification helps the resin keep its strength at higher temperatures; boron (B) does the same and also raises the friction coefficient. Chromite-modified novolacs raise the friction coefficient too.

| ELRIBOND 303 | 12–18 | 80–110 | 85–105 | 6.5 ± 0.5 | PVB modified |
High-bond pre-reacted novolacs
Our strongest binders. The hexamine curing agent is built into the resin during manufacture instead of being dry-blended afterwards, so it is spread evenly through every particle. The result is a denser crosslink network, higher mechanical strength and Tg, and better heat transfer during cure, so thick parts cure faster and more completely. Milled to the particle-size distribution you specify.
| Grade | Cure at 150 °C (s) | Moisture (%) | Hexamine (%) | Melting point (°C) | Character | TDS | Request |
|---|---|---|---|---|---|---|---|
| ELRIBOND 601 | 35 | < 1 | 14.5 | 85–90 | Fastest cure, highest hexamine | ||

Choosing a phenolic resin grade
| If you need… | Look at |
|---|---|
| A general-purpose brake pad or abrasive binder | Unmodified novolac powder resins (ELRIBOND 101–115) |
| Shorter press cycles and the highest strength | High-bond pre-reacted novolacs (ELRIBOND 601–604) or fast-curing grades 111–115 |
| Less brake noise and more comfort | NBR rubber-modified (201–207) or CNSL-modified (501–506) |
| Strength at high temperature | Phosphorus and boron-modified (401–405) or ELRIBOND 506 |
| A higher friction coefficient | Boron or chromite-modified grades (403–406), friction particles (901–904) |
| To add your own curing agent, or refractories | Hexamine-free novolacs (151–152) |
| A liquid binder for impregnation or wet mixes | CNSL liquid resins (801–804) |
How far the resin travels
Plate flow at 125 °C. Short-flow grades (12–25 mm) stay where they are put, which suits high-pressure moulding and fine mixes. Long-flow grades (50–100 mm) wet out fibres and coarse fillers more fully.
How fast it cures
Seconds to gel at 150 °C. Shorter gel times mean shorter press cycles and higher output. Fast-curing grades gel in 20–70 s; standard grades in 70–140 s.
How much curing agent
Hexamine crosslinks a novolac. Around 9 % gives full cure; lower levels release less ammonia and suit sensitive mixes. Hexamine-free grades let you add your own hardener.
How it handles and mixes
Higher melting points keep powder free-flowing in hot climates and storage; lower melting points start flowing sooner in the press.
Phenolic resin questions
What is phenolic resin used for in brake pads?
Phenolic resin is the binder that holds a brake pad together. The fibres, fillers, abrasives and lubricants are mixed with a novolac powder resin and hot-pressed; the resin melts, flows around the other ingredients and cures into a rigid, heat-resistant matrix. It keeps its strength at the high temperatures reached during braking, which is why it is used in almost all brake pads, drum linings and clutch facings.
What is the difference between novolac and resol phenolic resins?
A novolac is made with excess phenol and needs a curing agent, usually hexamine, to harden. A resol is made with excess formaldehyde and cures on its own with heat. Novolac powders are the usual choice for friction materials and bonded abrasives; resols are used where a binder without added hexamine is wanted.
How do I choose the right phenolic resin grade?
Start with flow (how far the molten resin travels before it gels), then cure speed (gel time) and hexamine content. Then pick a modification for the job: NBR or CNSL for lower noise and more comfort, phosphorus or boron for high temperatures, boron or chromite for a higher friction coefficient, and fast-curing or high-bond grades for shorter press cycles. Our team will recommend a shortlist if you tell us your application.
Can I get a sample of phenolic resin?
Yes. Use the sample request form on this page to ask for up to three ELRIBOND grades. We confirm the sample size, any cost and the courier details by email before anything is sent.
Do you export phenolic resin outside Ghana?
Yes. Elrisa supplies customers across Africa, the Middle East, Asia and Europe. We quote EXW, FOB, CFR, CIF, DAP or DDP terms, and tell you the shipping options for your port or city when we quote.
How much does phenolic resin cost?
Price depends on the grade, the quantity, the packaging and where it is shipped. Send the order form on this page with your grades, quantities and destination and we reply with a written quotation, usually within 24 hours. Full pallets of 500 to 1,250 kg ship most economically.
How should phenolic resin powder be stored?
Store it below 20 °C in the unopened original bags, in a dry place away from heat. Under these conditions most ELRIBOND powder grades keep for 6 to 12 months; the exact shelf life is on each technical data sheet.
Where can I download the phenolic resin technical data sheet (TDS)?
Grades marked with a TDS button in the tables on this page can be downloaded as PDF straight away. For grades marked On request, ask through the sample or order form and we email the data sheet.
