Starch-based aqueous adhesive compositions and uses thereof
The invention relates to starch-based aqueous adhesive compositions and uses thereof. Provided is an aqueous adhesive composition comprising highly branched starch (HBS) obtained by treatment of starch or starch derivatives with a glycogen branching enzyme, and further comprising a carboxymethyl (CM) polysaccharide derivative, such as a carboxymethyl ether of starch, cellulose or a combination thereof. Also provided is a method for adhering a first substrate to a second substrate, comprising applying to at least said first or said second substrate said starch-based adhesive, and a glued or glueable product obtainable thereby.
COLOR CHANGEABLE ADHESIVES AND METHODS OF MAKING SUCH ADHESIVES
Color changeable materials can be incorporated into adhesive materials while maintaining the efficacy and stability of the indicator. The indicators provide simple, reliable, and cost effective detection means for detecting ammonia and carbon dioxide, and may find use in applications such as food packaging and medical applications.
Photoactive bioadhesive compositions
A novel diazirine-based biocompatible polymer that can be used as on-demand or tunable bioadhesive and applied across various clinically important surfaces. The biocompatible polymer comprises a single strand of repeating units and up to 5,000 photoreactive diazirine groups covalently attached to it. A bioadhesive composition comprises the polymer of the present invention and suitable solvents, surfactants, stabilizers, fillers and other additives. The composition may additionally contain metallic particles of size less than 50 micron made of rare earth elements and has UV or NIR transparency less than 1 optical density unit per 1 centimeter. The poly-diazirine surface grafted thin films can be used for minimally invasive surgeries.
HPMC COMPOSITION FOR PROVIDING A HEAT-SEALABLE COATING ON PAPER AND BOARD
The present invention relates to an aqueous solution for forming a heat-sealable coating on a paper or board surface for reducing MOSH or MOAH migration, said aqueous solution comprising a thermoplastic hydroxypropyl methylcellulose (HPMC) in an amount of from 10% to 60% (w/w), wherein said HPMC has a DS(methyl) of at least 1.0 and an MS(hydroxypropyl) of at least 0.6, wherein DS is the average number of hydroxyl groups substituted by methoxyl groups per anhydroglucose unit and MS is the average number of moles of hydroxyalkoxy groups per anhydroglucose units, and wherein the viscosity of said HPMC is from 2 mPa.Math.s to 100 mPa.Math.s, determined as a 2% (w/w) solution in water at 20 C. according to Ubbelohde.
