SDS and COA
One safety data sheet per grade, one certificate of analysis per batch, batch number printed on the drum.
Grade A
Component A — the polyol behind one-component foam
Three seasonal variants of one base formula, built for lines that run window and door frames, curtain wall and export orders.
In the drum
What arrives, and what it is
This is the drum that goes into the white side of your line. Mixed with polymeric MDI at 40% or more of net weight, it gives a foam that cuts clean, holds its dimensions and passes a class I adhesion test on aluminium. Base, summer and winter variants differ only in catalyst and blowing balance, so your operators keep the same routine all year.
Packed in 200 L steel drums, five drums to the tonne. Every drum carries the batch number that matches the COA in your inbox.

| Viscosity at 25 °C (mPa·s) | 250–600 |
| Flash point (°C) | > 100 |
| Water content (%) | ≤ 0.15 |
| Storage | 5–30 °C, dry, sealed drum |
| Shelf life in the drum | 6 months, unopened |
| Packaging | 200 L steel drum × 5 = 1 t |
Typical values for orientation only. Final parameters are confirmed for the selected grade and your filling conditions.
Finished foam
What your line can reach with this grade
Typical values for the foam this component is formulated for, at the isocyanate share shown. Your numbers follow your can, your gas and your line — the sample is how we narrow them.
| Finished-foam parameter | Typical value |
|---|---|
| Isocyanate share of net weight (α) | ≥ 40% |
| Isocyanate : polyol ratio (β) | 0.9–1.3 : 1 |
| Apparent density, free rise (kg/m³) | 24–32 |
| Compressive strength at 10% (kPa) | 35–60 |
| Tensile adhesion on aluminium (kPa) | 85–120 · class I |
| Dimensional stability, 48 h (%) | ≤ 1.5 |
| Closed-cell content (%) | 85–92 |
| Yield per 750 ml can, 20 × 20 mm joint | 18–22 m |
| Shelf life, unopened can | 12–18 months |
Typical values for orientation only. Final parameters are confirmed for the selected grade and your filling conditions.
Fit and limits
A grade is defined as much by what it refuses to do
Where it fits
- Can types: 750 ml gun grade, 500–1000 ml; 240 g if your line is set for it.
- Seasons: base, summer and winter — tell us the ambient temperature at filling.
- Substrates: aluminium, uPVC, steel, masonry, wood, with the surface preparation in the SOP.
Where it does not
- Not a finished product: it needs an isocyanate and a filling line to become foam.
- B1 flame class needs a separate flame-retardant package; the standard grade is B2.
- Not for structural bonding — OCF seals and insulates, it does not carry load.
On the line
Four things that decide the first run
- Fill the first two drums strictly by the parameter card and log every weight. That log is what lets you loosen later.
- Hold the drum at 18–25 °C. Warm it slowly if the store is cold — never with an open flame, never in one spot.
- Flush the line when you change grades: 20–30 minutes, then recalibrate the fill weight.
- Keep one can per batch, cut it the next day and photograph the section. Two years of those photos end most quality arguments.
Documents
What travels with the drums
Form E and packing list
ASEAN origin documentation prepared before booking, so the customs broker is not chasing paper at the port.
Transport appraisal
Non-dangerous goods appraisal on request — the document a shipping line will ask for when the drum is a raw material.
Marks and traceability
Pallet marks in your format, retained samples kept two years, and a written answer if a batch ever needs investigating.
Questions
Three questions on this grade
Summer or winter — how do I choose?
Tell us the ambient temperature and substrate temperature at the filling head. Below 15 °C we ship the winter variant; above 28 °C with warm drums, the summer one. Between those, the base variant covers you.
Can I blend A and C in one drum?
No. Blend two grades and you lose the traceability that makes the datasheet worth anything. Order the grade you need; if a job sits between two grades, we will tell you which one to run and why.
What documents come with the drums?
SDS, COA for the batch, and Form E for ASEAN origin. A transport appraisal for non-dangerous goods is issued on request. Local finished-product certification stays with you; we supply the technical file you need to apply.
Send your can spec — we reply with the grade, not a price list.
