How to Compare Platinum Catalyst Quotes on an Elemental Platinum Basis

Buying platinum catalysts for addition-cure silicone

Ask the supplier to identify the catalyst and carrier and state how much elemental platinum is in each kilogram of product. Compare quotes once those details are clear. If a quote only says “high activity” or “active content,” ask whether the figure refers to the complex, another active ingredient or elemental platinum. Check purchase specifications and production performance separately.

IOTA-8100 platinum divinyltetramethyldisiloxane complex

Before ordering, obtain the technical data sheet for the quoted grade, the lot inspection items and written confirmation.

Comparing two quotes

Item	What the quote should state	Why it matters
Product identity	Full grade, complex, carrier and supplied form	Equal platinum content does not mean equal compatibility
Elemental platinum	ppm or percent by mass of supplied product, tolerance and test method	Quotes need the same basis
Purchase cost	Price per kilogram, packaging, quantity and delivery terms	Compare cost per unit of platinum, then check the amount needed to make acceptable parts
Lot documents	Technical and safety data sheets, lot test report and lot number	Trace samples and production deliveries

If both quotes give the elemental platinum mass fraction, divide the price per kilogram of product by that fraction to get the equivalent cost per kilogram of elemental platinum. Use it to compare quotes only. Even at equal cost, check working time, cure and cost per acceptable part in your current compound.

Turning trial results into acceptance criteria

1. Compare with the same lots of base silicone, crosslinker and filler. Keep mixing order and cure conditions consistent. Record elemental platinum relative to the mass of the whole compound.

2. Record when the mixture starts to thicken, whether parts demold at the actual mold temperature and cycle time, and whether any areas stay tacky. If only the tooling contact face fails to cure, check contact materials and contamination before adjusting dosage.

3. Put the agreed grade, elemental platinum specification, carrier and lot documents on the order. Compare the first production lot with the successful trial, retain a sample and record the lot number. Revalidate any change in carrier or supplied specification.

IOTA Silicone Oil (Anhui) Co., Ltd. provides solutions across the silicone value chain and can review catalyst raw materials and documentation against the addition-cure system and process. We do not supply complete formulations or formulation development.

Frequently asked questions

Q1 Is active content the same as elemental platinum content?

Only the supplier’s definition and test basis can establish that. List elemental platinum by mass of supplied product separately.

Q2 Can the quoted platinum ppm be used directly in production?

Check whether it refers to the catalyst or the entire compound. The denominators differ.

Q3 Can I switch between products with the same platinum content?

Compare carrier, compatibility, working time and cure in trials under the same conditions.

Q4 Do I need a trial if the delivery has a test report?

The report confirms lot specifications. After a source or specification change, trial the actual compound to check cycle time and finished parts.

Q5 Should I immediately increase dosage if some areas fail to cure?

Check mixing, temperature and contact contamination first. Increasing dosage is not a general solution to cure inhibition.
