Abstract:
An un-reacted substantially formaldehyde free curable binder solution for binding loose mutter consists essentially of a solution obtainable by dissolving a reducing sugar, an ammonium salt acid precursor, optionally a carboxylic acid or a precursor thereof and optionally ammonia in water.
Abstract:
A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of:
Forming mineral fibres from a molten mineral mixture; Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.
Abstract:
The corrosion of unprotected steel substrates causes damage that is costly to repair or replace. Current protective coatings predominately rely on environmentally harmful anticorrosive agents and toxic solvents to protect the underlying substrate. The use of lawsone (2-hydroxy-1,4-napthoquinone) together with a environmentally benign epoxy coating provides an environmentally-friendly alternative for common protective coatings. Microencapsulated lawsone embedded coatings allows the anticorrosive agent to remain dormant until released by damage and is then deposited directly onto the steel substrate. Both visual and electrochemical analysis shows that this self-protective scheme leads to 60% corrosion inhibition in a neutral salt water solution.
Abstract:
To provide a composition for powder coating material capable of forming a coating film having excellent water and oil repellency, capable of maintaining excellent water and oil repellency even when the surface is rubbed or when used in an environment in contact with water, and having excellent resistance to adhesion of organisms such that organisms such as mold, algae, etc. are less likely to adhere thereto; a powder coating material; and a coated article. The composition for powder coating material comprises polymer (A) composed of at least one member selected from polymer (A1) and polyvinylidene fluoride, and polymer (B). The polymer (A1) is a fluorinated non-block copolymer having units based on a fluoroolefin and units based on a monomer having a crosslinkable group. The polymer (B) is a fluorinated block copolymer having a segment (α) in which the content of fluorine atoms is at least 20 mass %, and a segment (β) in which the content of fluorine atoms is less than 20 mass %, wherein the difference in the numerical value of the content of the fluorine atoms represented by mass %, between in the segment (α) and in the segment (β) is at least 10, and at least one of the segment (α) and the segment (β) has a hydroxy group.
