Photoinitiator TPO Supplier in Malaysia
- Also known as
- TPO
- Diphenyl(2,4,6-Trimethylbenzoyl)phosphine Oxide
- Trimethylbenzoyl Diphenylphosphine Oxide
Photoinitiator TPO supplier enquiries in Malaysia are relevant to UV coating, ink, adhesive, electronics and additive-manufacturing formulators. TPO is diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, a Type I radical photoinitiator used to start curing when the formulation is exposed to a suitable light source.
Commercial TPO is normally supplied as a pale yellow powder. Standard, high-purity and formulation-specific grades can differ in assay, colour, volatiles, solubility and cure response, particularly in clear or pigmented systems. The photoinitiator should be selected with the resin, pigment load, film thickness and lamp or LED spectrum in mind.
Typical uses include UV-curable clear coats, pigmented coatings, printing inks, adhesives, sealants, electronics materials and 3D-printing resins. TPO is not the same product as TPO-L or photoinitiator 184, even though these materials may be evaluated within the same formulation-development programme.
Send the required photoinitiator grade, formulation, light source, purity, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.

Photoinitiator TPO grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Standard TPO UV-curing grade | pale yellow powder | — | Type I photoinitiator for UV-curable coatings, inks and adhesives where efficient through-cure and surface cure are required. | Confirm the required dry pack format with the quotation. |
| High-purity TPO grade | pale yellow powder | — | UV formulation work requiring tighter assay, colour and residual controls for clear or technically demanding systems. | Confirm the required dry pack format with the quotation. |
| TPO grade for 3D printing and pigmented systems | powder | — | Photopolymer resin, pigmented coating and additive-manufacturing formulations where the cure response is matched to the lamp or LED system. | Confirm the required dry pack format with the quotation. |

Common questions about photoinitiator TPO
What is photoinitiator TPO?
Photoinitiator TPO is diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, a Type I radical photoinitiator used to start curing in UV-curable coatings, inks, adhesives and photopolymer resins.
What is TPO used for in UV coatings?
TPO is used where the formulation needs efficient initiation and useful cure through the film, including clear, pigmented and selected 3D-printing systems. The lamp spectrum and resin package should be checked together.
Is TPO the same as TPO-L?
No. TPO is a solid phosphine-oxide photoinitiator, while TPO-L is a different liquid phosphinate photoinitiator. They have different physical forms and may change solubility, handling and cure behaviour.
Which TPO grade should I request?
State whether the application is a clear coat, pigmented ink, adhesive, electronics material or 3D-printing resin. Include the light source, colour requirement, target cure and any assay or residual limits.
What information is needed for a TPO quotation?
Provide the grade, form, formulation type, required purity, quantity, preferred packing and delivery location. Availability and supporting documentation are confirmed with the quotation.
