Methyl 1-Methylpyrrole-2-acetate:
Purity:>90.0%(GC)
M.F./M.W: C8H11NO2=153.18
CAS NO: 51856-79-2
Photosensitising dyes :
Name:Photosensitising dyes RST830
Properties:maximum absorption peak is 830nm. In infrared scanning,
Photosensitising dyes can adsorb the light energy and transfer
into heat energy.
Uses:used to produce temperature sensing glue in CTP temperature
sensing, dosage is 1¢¦3%.
Specification:Assay¡Ã98%

Appearance is
copper metallic glossiness
Packing:Inner bag is white PE bag , medium bag is black PE bag,
external bad is vacuum aluminum foil bag, 1kg/bag.
Specialty Resin for PS Plate
The series of products, manufactured are phenolic resins
and modified resins in the form of transparent lumps. The
softening points are in the range of 70-140¡ÆC, and viscosity in
5-13 mm2/s. They have excellent affinity, compatibility with
printing ink and fair resistance to alkali. They are grafted with
2-diazo-1-naphthol-5-sulfonyl chloride or used for the preparation
for the photosensitive film to give the product excellent
resistance to abrasion and printing life.
